Best Practices

Reference Photo Guidelines

• Quantity: Provide 3-10 reference photos for best results
• Angles: Include front, 3/4, and profile views when possible
• Lighting: Use well-lit photos without harsh shadows
• Resolution: Higher resolution photos produce better twins
• Consistency: Photos should show the same person at similar age
• Expressions: Include variety for expressive twin generation

Quality Optimization

• Mode Selection: Use max for final assets, eco for rapid prototyping
• Iterative Refinement: Use session_id to refine twins across multiple requests
• Specific Details: Describe exact requirements for lighting, background, expression
• Format Specification: Always specify aspect ratio and intended use

Identity Consistency

• Session Continuity: Use same session_id for all variations of one twin
• Reference Anchoring: Include original photos when requesting variations
• Style Lock: Describe consistent elements (lighting, background) across requests

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Mode	Best For	Speed	Quality
max	Final digital twins, production assets	Slower	Highest
eco	Quick previews, concept exploration	Faster	Good

Multi-Turn Twin Development

Use session_id to iteratively develop and refine digital twins:

Error Handling

Error	Cause	Solution
Failed to create prediction: HTTP 422	Insufficient balance	Top up at eachlabs.ai
